In this April 18, 2015, file photo, Jim Carrey arrives at LACMA's 50th Anniversary Gala in Los Angeles. Carrey said he was shocked and saddened to learn of the death of ex-girlfriend Cathriona White in September 2015, likening the news to being hit by a lightning bolt. Nearly a year later, her estranged husband sued Carrey for wrongful death and violation of the drug dealer liability act.

According to the suit, White, who committed suicide last September, was receiving prescription drugs from her Carrey, who used the "bogus name" Arthur King to obtain the illicit drugs. Burton, who is suing for wrongful death and violation of the drug dealer liability act, claims Carrey gave her the drugs "despite the fact that he knew full well that Ms. White was ill equipped to ingest and manage highly addictive prescription drugs outside the care of a licensed physician; was prone to depression; and had previously attempted to take her own life," according to court documents obtained by E! News.

According to the lawsuit, Carrey or his assistants monitored White's comings and goings from her house via surveillance cameras, but failed to report that she hadn't left the house in more than a day. They also state that the coroner "determined that the drugs had been obtained by defendant Carrey under a bogus name." As a result, Carrey tried to "cover-up his conduct and complicity in her death" by sending a "bogus text message on September 27, 2015 to White (who was already deceased) pretending as though he had misplaced the drugs and insinuating White may have taken them from Carrey without his knowledge..."

E! News has reached out to Carrey's rep and attorney for comment.

"We will be calling on the Los Angeles DA to open an investigation into Mr. Carrey's role in the death of Ms. White," Michael Avenatti attorney for the Burton, tells E! News. "We look forward to the evidence and facts supporting the allegations in the case coming to light."

When news of White's death broke, Carrey released an emotional statement. "I am shocked and deeply saddened by the passing of my sweet Cathriona," Carrey told E! News in a statement. "She was a truly kind and delicate Irish flower, too sensitive for this soil, to whom loving and being loved was all that sparkled. My heart goes out to her family and friends and to everyone who loved and cared about her. We have all been hit with a lightning bolt."
